The problem it solves

If your office or server runs on an internet connection without a fixed address, that address can change without warning, which breaks any remote access, VPN, or self-hosted tool depending on it. Manually checking and updating your DNS settings every time it happens is easy to forget.

Who it fits

Small businesses or IT staff running self-hosted servers or remote access from a location without a static IP.

How it works

  1. Every few minutes the system checks your current public IP address
  2. It compares this to the address currently on file with Cloudflare
  3. If the address has changed, it updates the Cloudflare DNS record automatically
What you get

DNS updates made without you checking your IP

Your Cloudflare DNS record stays current automatically, even when your internet connection's address changes without warning.

What you get

An always-current Cloudflare DNS record that points to wherever your server or office actually is.

What you need

A Cloudflare account with API access to the domain's DNS zone.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
